Danfoss MC300 Microcontroller Installation guide

Brand: Danfoss

Model: MC300 Microcontroller

Type: Installation guide

Danfoss MC300 Microcontroller is an environmentally hardened device, capable of controlling multiple electrohydraulic control systems either as a stand-alone controller or networked with other similar controllers. It features a multi-loop control capability for up to 4 bidirectional servo loops or 2 bidirectional and 4 unidirectional loops. The MC300 is ideally suited for dual-path hydrostatic propel systems incorporating closed-loop speed and horsepower control, and it can easily handle closed-loop position control systems using servovalves and proportional flow control valves.

DESCRIPTION

The MC300 Microcontroller is a multi-loop controller that is environmentally

hardened for mobile off-highway control system applications. The MC300

Microcontroller has the response speed and capacity to control multiple electro-

hydraulic control systems either as a stand-alone controller or networked with

other similar controllers via a high-speed Controller Area Network system.

The MC300 is ideally suited for dual-path hydrostatic propel systems incorpo-

rating closed-loop speed and horsepower control. Additionally, closed-loop

position control systems using servovalves and proportional flow control valves

are easily accomplished. Up to four bi-directional servo loops can be used.

The controller can interface with a wide variety of analog and digital sensors such

as potentiometers, Hall-effect sensors, pressure sensors, pulse pickups and

encoders.

The use of the I/O features and the control actions performed are defined by

firmware installed in the MC300's program memory. The firmware is typically installed by downloading the desired code from

another computer via the RS232 port. Re-programmability provides a high level of device function flexibility. Either factory or

in-field programming is possible.

The MC300 controller consists of a circuit board assembly inside of an aluminum die-cast housing. Three connectors,

designated as P1, P2 and P3 are provided for electrical connections. P1 (30 pin) and P2 (18 pin) are the main I/O and power

connectors; together they mate to the 48 pin board-mounted header, which protrudes through the bottom of the enclosure.

P3 is a circular connector for RS232 communications such as reprogramming, displays, printers and terminals.

FEATURES

• Multi-loop control capability for control of (4) bidirec-

tional servo loops or (2) bidirectional and (4) unidirectional

loops.

• Powerful 16 bit Infineon C167 microcontroller:

- Fast,

- Versatile,

- Controls multiple machine functions with fewer parts.

• Controller Area Network (CAN) provides high speed

serial communications with up to 16 other CAN compat-

ible devices and meets the speed requirements of SAE

network Class C specifications.

• Rugged aluminum die-cast housing withstands the en-

vironmental rigors typically found in mobile applications.

• Four-character LED display provides information for

setup, calibration, and troubleshooting procedures.

• Flash memory accessible through a dedicated RS232

port. Allows programming without changing EPROMs.

• Hardened power supply operates over the full range of

9 to 36 Volts with reverse battery, negative transient,

and load dump protection.

• Convenient RS232 port connector for data communica-

tion with other devices such as displays, printers,

terminals, or personal computers.

• Expandable via an internal 50 pin connector for custom

I/O boards.
